The Schedule referred to in these Lette -1'0 all whom it may concern:

. Be it known that- I, SAMUEL S. Fnnnis, ofthe city and State of New York, have invented and made au Improvement in Machineryfor Making Plate and Sheet- Glass; and I do herebydeclare the following to be a description. ofthe said invention, to the annexed drawing, making wherein- Figuie 1 is a vertical longitudinal section of said machine.

y Figure 2 is a plan ofthe same.

Figure 3 is an elevation of the side ofthe machine. Similar marks of reference denote the saule parts. The object of this invention is to roll out sheet-sor en a pair of rollers, and receive t platform, and straighten the and to regulate the temofthe machine. ntion consists in a device glass to a pair of rollers the saine upon a tia glass previous to its cooling, perature ofthe various parte The nature ofthe said inve for regulating the ow of the that roll outasheet ofuuiform thickness; and, in combination therewith, I make use of a platform .for receiving the glass, a roller for flattening the same, and an temperature ci' the opi-ou,A by the introduction of hot or cold air, and the speed of cooling of the glass.A l'

In the drawing, a a are frames sustaining the working parts of the machine; b and c are the, rollers for rolling out the sheet ci' glass.

These rollers are to he journals supporting them, hot air, superheated steam, steam, or water, may be caused to iiow through the rollers, for regulating their either to heat them previous to beginning the manufacture, or to cool -them during the manufacture ofthe plate or she at-glass.

The pipe-d d, connecting to t e respective journals l e e, by means of sleeves f that allow the rotation of the journal, and, at the sanne time, a free opening, may be employed for the inlet and outlet of the materials employed for regulating the temperature of the rollers and c.

The journal-boxes, justable by means of mede hollow, and also the in order that a current of I 2, of the roller c, are made adthe screws 3 3, so as to vary the thickness of glass rolled out between the rollers b and c, and the portions a' of the frame a may be removable and adjustable, so as to allow of the introduction of shorter rollers by the parts a being brought nearer together. l

.Above the roller b is an table, g, upon which are the movable side pieces lt, that can be ,adjusted to regulate the width of opening between which the melted upon the table g, posses .to the rollers b c,`and 4 is a clamping-bar to hold the ends of the side Apieces h in p ie.-

iis a gate, that is adjustable vertically,to regulate, generally, the thickness of the l yer or melted glass passing to the rollers b o.

Beneath the rollers b o, a mo provided. This is made ofmetel plates preperlyforniefl, and provided with slldcson their under sides to run vuele platform, la, is l rs Fatemi and para of the same upon the slidc-ways 5, and the platform is rendered as smooth and level as practicable,and the different plates or sections, lol-ming said platform, are to be hinged together to form an endless chain, passing over the pulleys Z ym., at any desired distance apart.

By means of the gearing n o p q, the rollers b and c are driven, and the shaft of the pulley 'm turned, and by means of crank-pins on the respective ends of the shais ofthe rollers m Z, placed at ninety degrees apart, andl the pairs on the respective sides connected by links, lr fr, the pulleyl will be revolved without the strain of so doing coming upon the platform-chain.

Rollers 4S at the edges of the platform, may be provided, running upon the ways 7, to support the platform-chain at the underside as it is drawn towards the pulley m.

.The surface of the platiorm k is to move at the same velocity as the glass is received from between the rollers o and c, and an adjustable or yielding roller, s, is employed to press the glass upon the platform, and straighten out :my bend or warp therein.

The plnti'orni itself may he of any length required for containing the plate of glass made from one charge of glass, or the ,manufacture may be continuous, the plate being out up at the clelveryend of the platform.

In order to regulate the temperature of the platform and the speed of cooling ofthe glass, I enclose said plat-- form by the casing t, and provide openings at -u ande, fitted with slides. to admit any desired amount of air to cool oli the said platform, more or less,as required; or, il nerxssary, heated air may hc admitted near the receivlngend.

"een opening is shown in the casing'at w, fig. 1,that allows air to poss in and cool the sheet of glass as it descends from the rollers be.

This mode of manufacturing plate or sheet-glass allows for the ornamertlng of' said glass, by the eugraving of any desired 'character of designs upon the roller c or o, to produce either relief or countersunk designs in the glass, anch-if desired, the glass might be marked .by this means, so as to facilitate the separation ofthe same into sheets of given sizes.

What I claim, ont, is-

l. A pair of rollers, formed hollow, and provided with means, substantially as speciied, for regulating their temperature, in combination with the inclined table g and movable side pieces h, for regulating the Width of the'noelted glass passing to said rollers, substantialiy as set forth.

2. The platform k hinged together, in comb o, and straightening-rolle stzintially as set forth.
